I own a very vicious betta named buddy. He's bit me twice, he has kills a whole tank full of fish, he flares at me, ect. To sum it all up he's a jerk and now lives in a 5 gal tank with no other fish except an algae eater. I did manage to train him a few tricks. He also knows his name. He also knows when I yell at him for flaring at me. He is a Wal-Mart rescue. I was buying supplies and saw him and fell in love. I don't support walmart in how they care for fish but it was love at first sight. I believe he thinks he is a dog.
